WARSAW, Poland (AP) — One is a restaurateur who fled Belarus when he learned he was about to be arrested for criticizing President Alexander Lukashenko. Another was given the choice of either denouncing fellow opposition activists or being jailed. And one is certain his brother was killed by the country’s security forces. What united them is their determination to resist Lukashenko by fighting against Russian forces in Ukraine. Belarusians are among those who have answered a call by Ukrainian President Volodymyr Zelenskyy for foreign fighters to go to Ukraine and join the International Legion for the Territorial Defense of Ukraine. And volunteers have answered that call, given the high stakes in a conflict which many people see as a civilizational battle pitting dictatorship against freedom. For the Belarusians, who consider Ukrainians a brethren nation, the stakes feel especially high. Russian troops used Belarusian territory to invade Ukraine early in the war, and Lukashenko has publicly stood by longtime ally, Russian President Vladimir Putin, describing him as his “big brother.” Russia, for its part, has pumped billions of dollars into shoring up Lukashenko’s Soviet-style, state-controlled economy with cheap energy and loans.
